What is the RPM of Emgrand GL at 120 km/h?

[Furtado]

When the Emgrand GL reaches a speed of 120 km/h, the engine RPM is 2200. The engine speed is related to the number of work cycles per unit time or the effective power of the engine, meaning the effective power of the engine varies with different speeds. Below is relevant information about engine speed: 1. The effective power specified on the engine product nameplate and its corresponding speed are referred to as the rated power and rated speed, respectively. 2. The operating condition of the engine at rated power and rated speed is called the rated condition. The rated power is not the maximum power the engine can produce but the maximum usable limit of effective power determined based on the engine's purpose. 3. For the same model of engine, the rated power value may differ depending on its intended use. Effective torque also varies with the engine's operating condition. Therefore, the maximum torque a car engine can output and its corresponding speed are used as indicators to evaluate the engine's dynamic performance. Typically, a speed sensor is used in conjunction with the signal teeth on the flywheel to measure the engine's speed.
